Electrochemical Copolymerization of Cross-Linkable Polythiophene and 9H-Fluorene

Abstract

The copolymerization of poly-3-ethyl-3-({[6-(3-thienyl)hexyl]oxy}-methyl)oxetane (PTO) and 9H-fluorene was successfully achieved electrochemically in CH₂Cl₂ containing 25 % boron trifluoride diethyl etherate (BFEE) (by volume) as supporting electrolyte by direct anodic oxidation of the monomer mixtures on platinum or an optically transparent ITO electrode. As-formed copolymer own the advantages of PTO, such as good electrochemical behaviours and excellent ambient stability. The structure of the copolymer were investigated by UV-VIS, fluorescence spectra and thermal analysis, respectively. The fluorescence spectra indicate that PPTOF films are yellow-light emitters. Thermal analysis studies confirmed PPTOF has a good thermal stability.
